Spors profiles several bloggers and the services available to generate revenue. Here are some revenue specifics to inspire you:

Rhett Butler, founder of Mongabay.com, a site with articles on rainforest conservation and other environmental issues, makes $15,000 to $18,000 a month from AdSense, using various types of ads. Mr. Butler says his blog currently gets about 1.3 million unique visitors per month.

He’s planning to eventually experiment with Google’s video player ads and create his own video content for the site. “The rainforest has always been my passion, but I never expected to make a living off of it,” says Mr. Butler, who quit his job as a product manager in 2003 when he realized he could make a living off his site.

Darren Rowse, the Melbourne, Australia-based writer of ProBlogger.net, a popular blog that teaches other bloggers how to make money, earned roughly $250,000 in 2007 off ads on three blogs he writes. Mr. Rowse says he makes the most off traditional display advertising, where advertisers pay a fee to appear, but he also has used affiliate ads and Google AdSense.

The great thing about Problogger.net is that the site is all about how to achieve the kind of success Darren has. Lots of great tips and techniques straight from the horse’s mouth.
